HENRY MYERS AND ABRAHAM VANZANDT, OF UPPER DARBY, PA.

IMPROVEMENT IN SPINDLES SPINNING-FRAMES, &c.

Specification forming part of Letters Patent No. 183,698, dated October24, 1876; application filed August 17, 1876.

To all whom it may concern:

' Be it known that we, HENRY MYERS and ABRAHAM VANZANDT, both of UpperDarby, in the conntyof Delaware and State of Pennsylvania, have inventeda new and useful Improvement in Bobbin-Spindles; and we do herebydeclare the following to be a clear and exact description of the naturethereof, sufficient to enable others skilled in the art to which ourinvention appertains to fully understand, make, and use the same,reference being had to the ,accompanying drawings, making part of thisspecification, in which- Figure l is a side elevation of the spindleembodying our invention. Fig. 2 is a central longitudinal sectionthereof. Fig. 3 is a horizontal section thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

It is well known that the contact of the bolster of a bobbin-spindlewears the latter so that the entire spindle becomes worthless. Ourinvention is designed to remedy this defect, and it consists of a sleeveencircling the spindle and carrying the bolster, whereby when the sleevebecomes worn it may be removed and a new sleeve fitted in its place,thus preserving the spindle proper. The sleeve will be prevented fromrotation by locking-engagement with the spindle, and from verticaldisplacement by the bobbin-rest.

Referring to the drawings, A represents the spindle; B, its pulley, andO the bobbin-rest.

A portion of the spindle above the pulley B is reduced in diameter, andon the same is fitted a removable sleeve, D, on which is mounted thebolster E. The inner face of the sleeve and outer face of the spindleare formed at adjacent points with a notch, a, and an engaging lug ortongue, b, respectively, whereby the sleeve and spindle will be locked,and rotation of the sleeve on the spindle is prevented. In order toretain the sleeve D in position, the bobbin-rest G will be screwed onthe spindle above the sleeve, so as to fit tightly against the sleeve.

It is evident that the spindle, which heretofore has been subjected towear by contact with the bolster E, is removed from said contact, and,as the sleeve D is interposed between the bolster and spindle, saidsleeve will be subjected to Wear. Wherefore, when the sleeve is worn, itmay be removed, the spindle remaining intact and unaffected, and a freshsleeve may be applied, the spindle, heretofore thrown away, thus beingpreserved.

In order to remove the sleeve, the bobbinrest 0 will be unscrewed orloosened, and the bolster and sleeve may then be slipped from thespindle.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

The bobbin-spindle A, with encircling sleeve D locked therewith, incombination with the locking bobbin-rest O, substantially as and for thepurpose set forth.
